Pumping fuel into the engine

Volkswagen lives of its class, the simplicity and & 39; economy. These characteristics are reflected in his models of vehicles. For example, VW vehicle base includes & 39; architecture, the fuel tank is located in a car & 39; opposite end of a reduction in the engine. Due to this distance, a specially designed, but in general-VW builds the fuel pump is necessary to the gas in the engine. There are two types of pumps VW: the fuel pump mechanics, in the carburetor term older models such as the Volkswagen Brasilia and combinations, and the electric pump fuel, in the latest electronic injection & 39; fuel consumption (EFI ) Cars.
Electric pumps, those who today are used & 39; today by VW, are almost always on the inner side of the tank & 39 d & 39; gasoline. This measure will prevent the steam d & 39; lock and keep the pump with low fuel consumption and a temperature controlled. The VW pump is a fuel-water turbine unit directly with an engine with a permanent magnet. This module uses the fuel in its coolant and oil. Fuel pumps are in electrical motors EFI, because they can high pressures are needed to make fuel. An electric pump VW fuel is usually in a position to about 90 pounds per square inch (psi) pressure of fuel. A check valve in the fuel to take if the pressure of the pump does not work. Another Hahn, the limiter pressure is the pressure of the pump on fuel consumption of the building, with a return flight to entrance near & 39 l fuel for the pressure of fuel in the rotor turns specifications.
As disc The roles are & 39; outside by centrifugal force and act as traffic d & 39, a seal. The roles in circulation, which in turn creates the post of pump-action & 39 d l & 39; development of fuel & 39, the port and forcing the fuel in the opening & 39; output and the system & 39; fuel system. If the pump is cut, the check valve in the fuel fixed, so the ban on the fuel back into the fuel tanks of the fuel pump. The check valve, the pressure in the fuel lines, " pressure. & quot; Maximum fuel pump pressure depends on the calibration of the & 39; limiter pressure. In a clogged fuel filter, such as pump fuel pressure on a pre-school, give a & 39; by-pass in & 39, opening fuel entrance near the pump by the pressure to limit.
Fuel failure of the pump & 39; n is not uncommon, especially in the cars on electronic fuel injection. Normally, when a fuel pump is not possible to spray a single trip and die and not restart. In essence, a car with a fuel pump do not act, as it is, from gas, even if natural gas in the tank. Failure of the fuel pump may be reviewed by the supply of fuel at the end of the system - unless fuel to the engine, fuel pump has very probably a failed.
Replacing-mail VW fuel pump can really difficult. The fuel pump assembly is usually simultaneously with the fuel tank d & 39; shipment. It should be made in the abduction & 39, the pump / sender Parliament is not damaged & 39; sender. Some vehicles have a sign d & 39; access to the fuel pump to deposit without the tank. VW will normally these groups. Some cars require a special tool to the fuel. D & 39; other cars have a sign d & 39; access to & 39; inside the cars which can be removed to pump fuel. D & 39; other vehicles require the fuel tank and emptied, or leaving before the fuel pump. This type of car is normally used for the hard work to replace a pump to fuel. Heavy & 39; ld & 39; development of a fuel pump May, but this car is & 39; efficient fuel consumption d & 39; approval.
